I sort of wanted some better indication for the headers to be links since somereason github doesn't underline them. But doing <ins></ins> on the link then would look funky with the subheading line. Past that was considering https://fontawesome.com/icons/arrow-up-right-from-square?f=classic&s=solid at the end of them, but then it'd seem like you should use that for all links, so I dunno its fine as is.

For me the first time looking at the page I was going to suggest you should add Guide to Git, because my attention was drawn more to the tip for the Guide to Contributing instead of the header's link. But I probably should just edit that article to better highlight guide to git on that page since all contributors need to follow those steps. It in a little git section doesn't make it seem relevant or important to contributing.
